ASSIGNOR TO HIMSELF AND J. C.

TILTON, OF PITTSBURG, PENNSYLVANIA.

Specification forming part of Letters Patent No. 58,710, dated October 9, 1866.

To all whom fit may concern:

Be it known that I, J. K. ANDREWS, of Antrim, in the county of Guernsey and State of Ohio, have invented certa-in Improvements in Railroad-Gar VVindOws; and I do hereby declare that the following is a full and exact description thereof, which will enable any one skilled in the art to make anduse my invention, reference being had to the accompanying drawings, forming part of my specification, in which- Figure 1 is a Side elevation of part ot' a railroad-car with my improvement attached, and Fig. 2 is a sectional view of the same through the line A B. Y

My invention consists in providing the windows of rail road-cars with a peculiar and novel side screen, which, by its position and shape, will cause the dust, gravel, coke, or other impurities loatin g in the air to be thrown away from the ear, instead of entering the window Ot' the said car, while it leaves perfect freedom for and improves the ventilation by the window.

It furthermore consists in arranging the said screen or screens so as to use them when the car is run in any direction, when the window is partly or quite up, and also so as to throw the screens out of the way when they are not used.

C is the body of the car as seen from the outside. D is the top or root' of the car. E E

are the panels Or side soli'd part bet-weon the windows. F F are thc windows. G G are the dormerwindows, (the sliding windows, being raised, are out of sight.) H H are the inside panels with upholstery.

K K are the screens, made ot' metal, wood, or made of glass, wire-cloth, and set in a frame. These screens K K are made of a curved shape, and placed as represented in the drawings, with the convex part turned to the inside of the car; and they can be placed at pleasure in any Ot the positions represented in the drawings or in any intermediate positions.

M M are grooves,which are a curved shape, corresponding to the shape of the screens K K. The solid panels E and H have between them a space, where the grooves M are placed, and the screens K K can slide freely in and out of these spaces, so as to be brought at pleasure in any of the desired positions.

When it is desired to put the screen K out of the way, it is done by pushing it, as represented in the middle panel Ot' my drawings, when the car is traveling in the direction ot' the arrow R. The screen is placed, as represented in my drawings, near that arrow, and the air traveling in the direction of the arrow S, any solid substances projected against the side of the car, if striking as represented by the dotted arrow T, will glance away from the line of its motion in the direction of the line T, and will be thrown out of the way.

The current of air induced by the motion of the car and the inclined screens K in the direction oi' the arrow T T will create a vacuum in the part S S, whichwill help to ventilate the car.

When the car is moving in the direction of the arrow V, the screen is to be placed, as represented, near that arrow, and the air, movin g in the direction of the arrow V, will have the same effect as already described.

I do not claim any novelty in providing carwindows with inclined side shields for driving away the dust or for ventilation purpose 5 but What I do claim as my invention, and desire to secure by Letters Patent of the United States, is-

The curved screens K K, with their convexV side turned inward, in combination with the curved grooves M M, situated between the panels H and E.
